We present theoretical findings concerning control of chaos for a wide and important class of dissipative nonautonomous systems capable of being studied by Melnikov's method and subjected to multiple harmonic chaos-inducing and chaos-controlling excitations. We demonstrate the effectiveness of the method in suppressing spatio-temporal chaos of chains of identical chaotic coupled oscillators -where coherent oscillations are achieved under localized control- through the example of coupled Duffing oscillators.
